项目摘要
This Grant Opportunity for Academic Liaison with Industry (GOALI) award supports fundamental research on enhancement of material shearing mechanisms in machining processes, using an approach that also controls friction. The chip in metal cutting is treated as a by-product, typically as waste. However, this new approach attempts to use the chip by applying tension and thereby reduce and cancel friction forces in machining. By attenuating friction forces, this new turning process assisted by chip-pulling can enable material removal with much lower cutting effort and energy; provide greater stability margins, longer tool-life, and facilitate high-throughput energy efficient precision manufacturing. A potential mechanism of suppressing the chip-jam with tailored cutting tool geometries is also likely with the new approach. Collaboration with a partner from US aerospace industry will help ensure the technology transfer. The research focus is to investigate how tension applied on the cut chip during machining processes affects cutting mechanics and dynamics. Effective use of the cut chip requires robust control of its flow. Micro-textured tools will be designed to control and navigate the chip flow to realize application of tension. Analytical models will be developed to understand the link between micro-grooved tool geometry to the chip flow mechanics and chip flow controllability. The effect of applying tension on the cut chip will be investigated. Tension applied to the chip cancels the friction force on the rake face and reduces the cutting effort while improving cutting mechanics. Analytical models and experimental characterization will be performed to understand the effect of pulling the chip on resultant cutting forces, cutting energy, the dynamic relation amongst them, and the limitations. Based on this understanding, chip tension will be introduced as an innovative process control parameter to improve static and dynamic characteristics of the machining process. Machining of precision parts can be realized with lower form errors by minimizing overall cutting forces through chip tension and force control. Reduced machining cycle times and increased material removal rates can be achieved through greater chatter stability margins that can be attained by modulating the chip tension jointly with process parameters.
这项学术与工业联络资助机会(GOALI)奖支持在机械加工过程中使用控制摩擦的方法增强材料剪切机制的基础研究。金属切削中的切屑被视为副产品,通常被视为废物。然而,这种新方法试图通过施加张力来使用芯片,从而减少和消除加工中的摩擦力。通过减小摩擦力,这种新的车削工艺在切屑牵引的辅助下,可以以更低的切削力和能量去除材料;提供更大的稳定裕度,更长的刀具寿命,并促进高通量节能精密制造。新方法也有可能通过定制切削刀具的几何形状来抑制切屑堵塞。与美国航空航天业合作伙伴的合作将有助于确保技术转让。研究的重点是研究切削过程中施加在切屑上的张力对切削力学和动力学的影响。有效地利用切屑需要对其流量进行强有力的控制。设计微纹理工具来控制和引导切屑流,实现张力的应用。将开发分析模型,以了解微槽刀具几何形状与切屑流动力学和切屑流动可控性之间的联系。研究了在切屑上施加张力的效果。施加在切屑上的张力抵消了前刀面上的摩擦力,减少了切削力,同时改善了切削力学。分析模型和实验表征将被执行,以了解拉切屑对合成切削力,切削能量,它们之间的动态关系,以及限制的影响。基于这种理解,切屑张力将作为一种创新的过程控制参数引入,以改善加工过程的静态和动态特性。通过切屑张力和力的控制,使整体切削力最小化,从而实现精密零件的低形状误差加工。通过调节切屑张力和工艺参数,可以获得更大的颤振稳定裕度,从而减少加工周期时间,提高材料去除率。
